| PURPOSE: To forge a part large and complicated in shape at a high temperature in the atmosphere by coating a billet with metallic material and forming a forging die of an oxidation-resistant, high temperature and high strength martial. CONSTITUTION: When a Ni base super heat-resistant alloy billet higher than 1000°C in superlasticity generating temperature is hot-forged in the region of superplasticity generating temperature, the billet is coated with metallic material having a melting point higher than the forging temperature and the forging die is formed by oxidation-resistant, high temperature and high strength material, the coated billet is heated to the superplasticity generating temperature and hot-forged by the forging die heated at a high temperature in the atmosphere. Thus, a part large and complicated in shape can be hot-forged in the atmosphere. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE:To provide a titled device which causes superplastic deformation in a work by heating dies to a prescribed temp. in a hermetic chamber in which a manipulator can be inserted and an upper die provided with a heater can be moved upward and downward, maintaining atmosphere of a vacuum or a specific gas therein and pressurizing the dies. CONSTITUTION:An upper die vessel 1 fitted airtightly to a lower die vessel 5 is descended and dies 2, 6 are heated to a prescribed temp. by a heater 9 enclosed with a heat insulating material 11. The vessel 1 is moved upward and a work is inserted into the vessel by a manipulator B through a sluice valve part. The work is subjected to superplastic forging by the dies 2, 6. The atmosphere in the hermetic chamber is evacuated to a vacuum by a vacuum pump 15 according to need or a specific non-oxidative gas is fed therein from a cylinder 12 and is regulated to a prescribed internal pressure by a pressure regulating valve 14. Intended hot superplastic forging is accomplished under the specific temp. and for working time within a specific temp. range by the above-mentioned operation. | ||||||

| PURPOSE:To lessen reduction of the hardness of a die material and to prevent wear and scuffing, by accelerating a pressurizing cooling liquid by high-pressure air current and blowing continuously against a forging die face so that a wet cooling film is formed always on the forging die face. CONSTITUTION:A cooling liquid in a liquid tank T is pressurized to a specified pressure by a pressurizing pump P and discharged to the outside of the pump P. The liquid is then controlled to a specified flow rate by a flow rate controlling valve V and allowed to flow in the holder 3 of a lower die 2 through a flow passage 6. Then, the pressurized cooling water is accelerated by high pressure air that flows upward through a flow passage 5, and jetted from a nozzle 7, and blown against the surface of an upper die continuously at high pressure and high speed. Consequently, a wet cooling film is always formed on the surface of the upper die, and the excessive liquid is blown to the outside of the die and recovered in the liquid tank T. A similar device is attached to the holder 4 of the upper die 1 to form a cooling film on the surface of the lower die 2. | ||||||

| PURPOSE: To prevent the adverse influence of high temp. heating of dies upon respective parts by projecting the working ends of the dies to a central side from the inside end surfaces of packers and supporting the dies and the packers with steel balls. CONSTITUTION: A motor is started, and a work 36 is heated and is fed into dies 16, 16a, 16b like an arrow 37 to heat the working ends of the dies to about 800°C. Spindles 11, 11a, 11b are rotated in an arrow 38 direction by a pulley, a belt 35, and a pulley 8. As the spindles rotate, the packers 13, 13a, 13b are forced out in the central direction, by which the dies 16, 16a, 16a are also forced in the same direction and the work 36 is worked to a prescribed outside shape. In this stage, the dies and the packers are in linear contact with each other through balls 18, 22 and liners 12, the high temp. heating of the dies does not give any adverse influence upon the respective parts.
